nariiy obtained from fats or oils or directly from stcarin, and either heat it suiiiciently to liqucfy it or take a hot saturated solution of it in alcohol or other solvent and mix it thoroughly by stirring with the dry crystallized or powdered. sulfite, using the two ingredients in the proportion of about one part, by \vcigl'it, of stearic acid to threc parts of the suhite. Before the mixture so formed has cooled it may either be molded into the form of briquets or granulated by stirring, or it may be left in the form 01 a solid-mass of the shape of the interior of the containing vessel. This material I name saccharii'er. In any of these forms the material is in suitable condition to be used for clarifying crude saccharine juices or impure sugar solutions.

in carrying out this invention after a sum cient amount of magnesia or lime has first been mixed with the juice to neutralize the organic acid which it contains and When the liquid has been heated to a temperature of about 180 Fahrenheit the clarifying agents above described are introduced into it and used in quantities proportionate to that of the impurities present in the juice as ascertained by previous test, (as byprecipitatioar by alcohol or subacetate of load.) In general one pound of theniixture vill be sufficient for about two hundred gallons of a juice of mediuniquality. The juice is then brought to the boiling temperature, the scum removed, and it is then allowed to stand at rest for a sufiicient time to allow the sediment to subside, and the clear juice is then run oii and evaporated to a density to produce sugar or syrup. This material when thus assisted by heat has the effect of break ing up and uniting with and rendering insoluble the impurities ordinarily found in saccharine juices or impure sugar solutions, thus defecating then]. at once. Before being introduced into the heated saccharine solu" tion the substances in the cornpound simply constitute a mixture and have no chemical reaction upon each other, and in that form both will retain their characteristic chemical properties unchanged for any length oitiine,- and the compound will be in a convenient condition for transportation or for inunedi ate use.

Be it known that 1., Farmers L. STEWART, of Murrysville, l/Vestmoreland county, Pennprovement in Deiecating saccharine Liquids, of which the following is a full, clear, and enthe process of their manufacture into sugars and syrups; and it consists in the use of stearic acid, and preferably sulfite of magneuced into the saccharine juice at such a temperature as will enable them to exercise their special ollect upon the impurities in the juicc -viz., the stearic acid should be introduced first when the juice has reached a temperature of not less than 150 Fahrenheit, but preferably about 180 Fahrenheit, and should be succeeded by the addition of sullitc of magnesium, so that these substances may be simultaneously present in the juices. The two substances thus used are thoroughly incorporated with the juice by agitation till it hasrcached the boiling temperature. For the sul'litc of magnesium the sulti'te of one of the other-metals of the alkaline earths may be substituted. These ingredients are preferably used in about the proportions of one part, by Weight, of stearic acid to three parts of the sulfite. Toe/n1 pound of stearic acid and three-iourths'o'f a pound of the sul'fite to about two hundred gallons of the saccharine l'piid as ordinarily obtained from the stalks. The abovenamed proportions are those required for average conditions, the necessary amount of the defecating compound varying from one pound for one hundred gallons of juice of in-- ferior quality to one round for three hundred gallons of juice of the best quality. In all cases the amount of defecating compound used should be sufficient to remove the impurities and should be in proportion to the total organic matter other than sug f which is contained in the juice to be defecated, as may be ascertained by previous test. While these substances may be added separately, as above described, it is usually more convenient to use them in the form of a mixture which I prepare by taking steai'ic acid, either hen used under the above-described corn in the puri'liediorin or as associated with ditions, the result of the reaction of the conniargaric, palmitic, or oleic acids as ordil stituents of the compound upon each. other :Sin

and upon the.ir'n urities commonly resent in. the saccharine iquid is such that w en the liquid is reduced by rapid evaporation to the condition of adense syrup or masse-cuite it is then cheaply and expeditiously clarified and refined, no in urious substances being left in the solution.
